Embodiment

[0024] The fertilized eggs are obtained from the Chinese horseshoe crab spawning pond in the breeding workshop by self-mating and spawning. Embryo cultivation containers are white rectangular plastic pots with specifications of 36cm×28cm×13.5cm (hereinafter referred to as pots), 17cm×7cm round plastic baskets (hereinafter referred to as small baskets), and rectangular large baskets of 45cm×32cm×17cm (hereinafter referred to as large baskets). ), a 40cm×30cm×12cm black plastic basket (hereinafter referred to as the basket).

[0025] 2. Method:

[0026] Six different environmental factors, including pots on the bank of the nursery pond, pots in the water, baskets in the water and sand of three types of thickness, were used to affect the cultivation of horseshoe crab embryos.

[0027] Put the fertilized eggs produced by the same pair of horseshoe crabs in the same batch into white pots and small baskets respectively. Put 100 ovums in each white pot, water depth is 2.5-3.5cm, al...

Abstract

The invention relates to a method for accelerating the embryonic development speed of horseshoe crabs of China by controlling the environmental factors. The method is characterized by comprising the steps of culturing fertilized eggs produced after copulation of the horseshoe crabs of China in a rectangular mesh basket under the conditions that the water temperature is 27.5-31 DEG C, the pH value is 7.8-8.0, the dissolved oxygen is 6.3-7.0, the illumination is 60-3000 lx and the salinity is 32-35 per thousand; putting the rectangular mesh basket into a culture pond, wherein the water depth of the culture pond is 0.5-2.0m. After the method for accelerating the embryonic development speed of the horseshoe crabs of China by controlling the environmental factors is used for culturing the horseshoe crabs of China, the horseshoe crabs of China generally begin to take off the membrane and are incubated from about the thirtieth day, so that time is shorter; therefore, the breeding time is shortened, the survival rate is improved, and the breeding cost is saved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for improving the development speed of Chinese horseshoe crab embryos by controlling environmental factors. Background technique [0002] Chinese horseshoe crab (Tachypleus tridentatus), which belongs to the phylum Arthropoda, has the subphylum Chelieerta, the class Merostomata, the order Xiphosura, and the family Limulidae. During the development of embryos and early larvae of horseshoe crabs, there is a trilobite stage, which is a close relative of the trilobites that appeared in the Early Cambrian (about 570 million years ago) and went extinct in the late Permian (250 million years ago). Limulus is now the only remaining animal of the class Lismus, which began in the Cambrian period, flourished in the Silurian and Devonian (435-360 million years ago), and began to decline in the Mesozoic (about 240 million years ago) , so far only horseshoe crabs remain. The earli...
